Video: Titan Supercomputer Session Showcases Science on GPUs

In this video from GTC 2012, Jack Wells, Director of Science at ORNL introduces a series of talks on the research that will be accelerated by the hybrid Titan supercomputer.

The whole system is an upgrade,” said Jack Wells in describing how Oak Ridge’s current Jaguar supercomputer is being transformed into Titan. ORNL is transitioning from Cray’s XT5 compute blades to their XK6 compute blades, which use hybrid chipsets comprised of AMD Opteron CPUs and NVIDIA Tesla GPUs. Application benchmarks conducted thus far have demonstrated that the XK6 is yielding performance improvements ranging from 50 percent to 230 percent compared with the XT5.

"Exascale computers are going to deliver only one or two per cent of their theoretical peak performance when they run real applications; and both the people paying for, and the people using, such machines need to have realistic expectations about just how low a percentage of the peak performance they will obtain."
